IMPROVEMENT IN DIES FOR MAKING FIFTH-WHEELS OF CARRIAGES.

Specification forming part of Letters Patent No. 132,705, dated October29, 1872.

To all whom it may concern:

Be it known that I, DARIUS WILcox, of Birmingham, in the county of NewHaven and State of Connecticut, have invented a new Improvement inForging Blanks for Top Plates of Fifth-Wheels; and I do hereby declarethe following, when taken in connection with the accompanying drawingand the letters of reference marked thereon, to be ai'ull, clear, andexact description of the same, and which said drawing constitutes partof this specification and represents, in-

Figure 1, a perspective view of the upper die; Fig. 2, a perspectiveview. of the lower die; and in Fig. 3, a perspective view of the biankproduced by this die.

This invention relates to an improvement in forging top plates offifth-wheels for carriages, such as are known to the trade as the Derbyfifth-wheel, and which are constructed with projections upon the upperside to receive the head-block. These ends have heretofore been forgedand wrought by hand, a laborious and expensive operation.

The blank is shown in Fig. 3, a a being the two projections, forming aspace, A, between, into which the head-block'sits. One end, B, is thendrawn out into any desired form for the forward ends of the plate,usually of some ornamental form. The other end, C, is welded to the topplate of the fifth-wheel, one of these blanks being used for each end ofthe top plate. The object of this invention is to construct this blankat a single blow, greatly reducing the expense of manufacturing thispart of the carriage. 1) is the lower die, which is formed with astraight groove, E, through the center, corresponding to the body of theblank. The upperdie F is formed with a groove through the centercorresponding to the groove in the lower die to form the upper side ofthe blank, and in this groove two recesses, d, corresponding to theprojections a, are made, so that when heated the bar is placed in thelower die and the upper die struck thereon, the metal will be thrownupinto the recesses d in the upper die and form the projections a a on theblank, and also leave the two ends in proper form for drawing out andfor attachment to the plate.

I claim as my invention- The die-blocks F D, with the cavitiesdescribed, for the purpose of forging blanks for the top plates offifth-wheels, as set forth.

DARIUS WILOOX.
